These data originate from soil samples collected on several field campaigns, aiming at identifying impacts of large herbivore activity on soil carbon storage and degradation in...

The data contains water chemistry and spectral catchment NDVI for 14 streams in Zackenberg Valley in Northeast Greenland, sampled summer 2021 from 10th July to 15th September....

Arctic sea surface microlayer (SML) and bulk water samples were collected during the PASCAL campaign in the Fram Strait, Barents Sea and central Arctic Ocean on board the German...

During the Maria S. Merian cruise MSM95 to the Fram Strait in 2020, water samples were collected from nine stations using a CTD rosette sampler (SeaBird SBE 911Plus). Samples...

Algal pigment concentrations were retrieved from meltponds and leads, during Leg 4 and 5 of the MOSAiC expedition (Multidisciplinary drifting Observatory for the Study of Arctic...

The Arctic is one area that has been affected by rising temperatures, leading to an increase in meltwater in the water column. During the months of June/July 2019, fronds of the...

This dataset contains HClO3 and HClO4 (30min-averaged) data, measured with a nitrate-chemical ionization atmospheric pressure interface time-of-flight mass spectrometry...

As part of the MOCCHA 2018 campaign onboard I/B Oden, Sea surface microlayer (SML) and underlying water (ULW) samples were taken from an open lead system in the central arctic....

Diatoms account for up to 40% of marine primary production and require silicic acid to grow and build their opal shell. On the physiological and ecological level, diatoms are...

The concentration and carbon isotope delta (δ13C) of methane (CH4), the water mass tracer δ18O(H2O), and nutrient concentrations were measured in seawater during the Polarstern...

The project AWI-funded AMUST project aims at understanding at current and future controls of Arctic spring blooms and concurrrent effetcs on biogeochemistry,by combining...

We present simultaneous measurements of dissolved CO2, CH4 and N2O from lake, pond and low order fluvial systems across two summers (2016-2017) in the Indigirka River lowlands...

Between 2006 and 2015 inorganic and organic hydrochemical parameters and stable water isotope characteristics were measured in lakes and ponds in continuous permafrost...
